History dependent crystallization of Zr41Ti14Cu12Ni10Be23 melts [PDF]

, 2000
The crystallization of Zr41Ti14Cu12Ni10Be23 (Vit 1) melts during constant heating is investigated. (Vit 1) melts are cooled with different rates into the amorphous state and the crystallization temperature upon subsequent heating is studied. In addition,

Low-Temperature Crystallization of Amorphous Silicate in Astrophysical Environments

, 2010
We construct a theoretical model for low-temperature crystallization of amorphous silicate grains induced by exothermic chemical reactions. As a first step, the model is applied to the annealing experiments, in which the samples are (1) amorphous ...

The Physics of Crystallization from Globular Cluster White Dwarf Stars in NGC 6397 [PDF]

, 2009
We explore the physics of crystallization in the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from proper motion cleaned Hubble Space Telescope photometry of the globular cluster NGC 6397.
